Tampa Bay (Fla.)
a stormwater management and rainwater harvesting system and a solar panel array
at its ultragreen inner-city development in Tampa. The stormwater management
system is located under the new community park. It controls and harvests
stormwater runoff to irrigate the new green space.
Precast (Auburn, Wash.) designed and provided the modular underground retention
structure for the new stormwater management system, which was engineered by
Cardno TBE (Clearwater, Fla.). The system will store, treat, and harvest
stormwater runoff on the 11-ha (28-ac) site. The precast-concrete retention
system manages and controls the volume and discharge timing of stormwater
runoff. The engineered design maximizes storage volume while minimizing the
project’s footprint and cost. Furthermore, the design allowed for a quick and
1672-m2 (18,000-ft2) stormwater-retention-harvesting
system includes a Storm Capture® vault composed of 250-mm-tall
(10-in.-tall) Storm Capture modules that can hold up to 934 m3
(33,000 ft3) of water before recycling it for irrigation use, two
nutrient-separating baffle boxes by Suntree Technologies (Cocoa, Fla.) with
adjacent sediment chambers for pretreatment, and harvesting and irrigation
equipment assembly by John Deere Green Tech (Irvine, Calif.). All surface
stormwater is collected from the site, piped into the baffle boxes and sediment
chambers, and stored in the Storm Capture modules for irrigating the site
(Frankenthal, Germany), a supplier of pumps and pumping
equipment, is supporting flood relief efforts in the city of Halle, Germany.
Entire streets were flooded and tens of thousands of Halle residents faced the
threat of evacuation, so KSB helped by providing pumps and food supplies. About
30,000 residents of Halle–Neustadt were told to evacuate their homes, as two
local dikes were in danger of being breached. The facility where KSB’s
wastewater products are made is located in Halle; however, the KSB facility,
which is located on higher ground, was not at risk from the flooding.
Village of Bloomingdale, Mich.,
awarded a contract to
Biowater Technology (Tonsberg, Norway), a provider and manufacturer of advanced
biological wastewater treatment processes and equipment for municipal and
industrial facilities, to supply a Complete Mix Fixed Film (CMFF®)
biological treatment process.
water resource recovery facility has unique challenges associated with seasonal
fluctuations from regional school and food-processor discharges. The existing
lagoon could not meet new ammonia limits, and the cold weather in Bloomingdale
has a significant impact on wastewater treatment efficiencies. Removing such
contaminants as biochemical oxygen demand, total suspended solids, and other
nutrients from wastewater is necessary regardless of weather conditions.
municipality selected CMFF, which is based on the moving-bed biofilm reactor
concept. Bloomingdale decided a three-stage aerobic CMFF process followed by
gravity clarification design would be the best solution to overcome the
challenges of seasonal fluctuations and cold temperatures.
(Montreal), a subsidiary of Veolia Water Solutions &
Technologies (Paris), was awarded a contract to provide a Hydrotech Discfilter
system for the upgrade and expansion of the Village of Maybrook, N.Y., water
resource recovery facility project. The Maybrook facility will expand its
capacity and be upgraded to meet more-stringent State Pollutant Discharge
Elimination System requirements. The Hydrotech Discfilter system, which will
consist of two units, each sized to treat a peak flow of 6813 m3/d
(1.8 mgd), is designed to provide an effluent total suspended solids of less
than or equal to 5 mg/L. The facility will continue to discharge to a tributary
of Otter Kill Creek.
water company Cadagua
(Bilbao, Spain) was selected to
retrofit its Valdelentisco desalination facility with PX® technology
by Energy Recovery Inc. (San Leandro, Calif.), an industry leader in capturing
reusable energy from industrial fluid flows and pressure cycles.
1 of this new project, which involves a retrofit of two reverse-osmosis trains,
is one of many joint projects by Cadagua and Energy Recovery. Part of a larger
trend to retrofit desalination plants around the world, this project highlights
the viability and sustainability of desalination as a solution to the ever-growing
strain on available freshwater resources. By retrofitting and upgrading
technology, facilities and municipalities can save money and increase
chose the PX technology not only because of the estimated annual savings for
Phase 1 but because the facility will not have to replace its existing pump
system, adding to the overall increase in savings.
in southeastern Spain, the Valdelentisco desalination facility has a potable-
and irrigation-water production capacity of 140,000 m3/d, making it
one of the largest desalination facilities in Europe.
(Fort Lauderdale, Fla.) upgraded a water-recycling
facility in Hawaii with the MaximOS™ sodium hypochlorite, onsite-generation
disinfection system that is designed to deliver immediate operating cost
savings while maintaining the highest water quality standards.
The upgrade is a result of Parkson’s
partnership with the water-recycling facility operator as part of a
public–private partnership with local authorities in Oahu.
chose MaximOS to replace the existing sodium hypochlorite system, which
incurred a substantial cost burden because of the high price of chemicals on
the island. By transitioning to the Parkson system, which relies on common
salt, the facility will realize substantial operational savings.
upgrade includes four MaximOS units that use self-cleaning electrolytic cells
to ensure proactive maintenance. In this configuration, the unit delivers long
life cycles and ease of operations, in part because it does not require
acid-washing during normal maintenance. The latest generation of MaximOS models
places a premium on self-sufficiency to minimize the amount of labor needed for
operations and care.
The 49,210-m3/d (13-mgd) facility
relies on MaximOS and other technologies to facilitate irrigation by the
municipal government and supply process water for a power plant and oil
recently awarded the Ak-Chin Indian Community’s surface
water treatment plant, featuring the GE Water & Process Technologies
(Trevose, Pa.) ZeeWeed 500 advanced treatment technology, with the 2013 Water
Project of the Year Award. The new plant, commissioned in 2012, has a capacity
of 8516 m3/d (2.25 mgd) and provides drinking water to community members
and Harrah’s (Las Vegas) Ak-Chin Casino. It also provides sufficient capacity
to meet the needs of existing commercial operations, as well as future
is the first surface water treatment plant for the Ak-Chin Indian Community,
located in the Santa Cruz Valley of southern Arizona. The plant takes advantage
of its surface water allotment of Colorado River water supplied via the
Maricopa–Stanfield canal system and the Central Arizona Project canal, which
gives it a secure source of water, allowing for the population to properly plan
for future growth and expansion.
company also provided the technology for the Ak-Chin Indian Community’s nearby
membrane bioreactor water resource recovery facility (WRRF), which provides
Arizona Class A+ effluent for water reuse and recharge. The WRRF won an
international award and multiple state awards. Carollo Engineers (Walnut Creek,
Calif.) is responsible for the award-winning facilities.
